KEO Four-Flute Machine Countersinks.

Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a conical recess for flat-head screws in metalworking. Its 82-degree angle matches standard flat-head fastener angles, making it ideal for deburring and countersinking holes in industrial manufacturing and maintenance applications.

What are the specifications of the KEO 917-000-286 countersink?

The KEO 917-000-286 is an 82°, 4-flute machine countersink with a 1 1/4 in body diameter. It features a TiN-coated cobalt construction for wear resistance and extended tool life. This part is designed for use in drill presses and CNC machines for precision countersinking.

Where to buy the KEO 917-000-286 countersink worldwide?

You can source the KEO 917-000-286 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this KEO tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the fastener head angle—82° for standard flat-head screws. Match the body diameter to the hole size and material. For harder materials like stainless steel, choose TiN-coated cobalt tools like the 917-000-286 for better heat resistance and longer tool life.
